Air disinfection and sterilization is an important means to ensure indoor air quality and prevent the spread of diseases.

There are many kinds of traditional air disinfection methods, each of which has its unique advantages and scope of application.

At present, there are a variety of air disinfection sterilization methods on the market, which is more effective?

Here are some common traditional air disinfection methods and the differences between them:

1. Ultraviolet disinfection:

Ultraviolet disinfection is a common method of air disinfection. Ultraviolet rays have a bactericidal effect and can destroy the DNA structure of bacteria and viruses, thereby achieving a sterilization effect. The advantages of ultraviolet disinfection are short disinfection time, high sterilization efficiency, and no secondary pollution, but its main disadvantage is that the sterilization spectrum is narrow, and the effect on some ultraviolet-resistant bacteria and viruses is not good; the disinfection time is longer, and it cannot be completely eliminated Viruses and bacteria. In addition, ultraviolet disinfection requires direct irradiation to work, so the angle and distance of irradiation need to be considered when using it.

2. Ozone disinfection:

Ozone disinfection is also a common method of air disinfection. Ozone is a strong oxidant that can quickly kill bacteria, viruses and other microorganisms in the air. The advantages of ozone disinfection are wide sterilization spectrum, high disinfection efficiency and short disinfection time, but its main disadvantage is that it will produce secondary pollution in the disinfection process, causing certain harm to humans and the environment. Therefore, when using ozone disinfection in homes and offices, it is necessary to pay attention to the concentration of ozone disinfectant and disinfection time, while maintaining good ventilation.

3. Chemical disinfectant disinfection:

Chemical disinfectants are a common method of air disinfection, which can kill bacteria, viruses and other microorganisms in the air. The advantages of chemical disinfectant disinfection are wide sterilization spectrum, high disinfection efficiency and convenient use, but its main disadvantage is that harmful substances may be produced during use, causing certain harm to the human body and the environment. When using the need to pay attention to the corrosive and irritating chemicals. Therefore, when using chemical disinfectants, it is necessary to pay attention to the amount of use and disinfection time, while maintaining good ventilation.

4. Filter sterilization:

The bacteria and viruses in the air are filtered out through an air filter. It is a kind of equipment that can filter, absorb and decompose bacteria, viruses and other microorganisms in the air. Filter sterilization has the advantages of safety, environmental protection, and no side effects, but its main disadvantage is that it requires regular replacement of the filter and maintenance, otherwise it will affect its purification effect and service life. And this kind of equipment is mainly filtration, adsorption and other functions, can not kill bacteria, viruses and other harmful microorganisms in the air.

5. Negative ion purification:

Negative ion technology is a non-chemical method that does not produce harmful substances and is environmentally friendly. Negative ions can be combined with dust, smoke and other particles in the air to form a precipitate, thereby purifying the air and improving air quality. Simple operation, user-friendly. Disadvantages: 1. Ozone production: The negative ion generator may produce a certain amount of ozone in the process of generating negative ions. If the concentration of ozone is too high, it may have a negative impact on human health. 2. High energy consumption: The negative ion generator needs to consume a certain amount of electric energy to produce negative ions, so it is necessary to pay attention to energy saving during use. 3. High maintenance cost: The service life of the negative ion generator is relatively short, and the filter screen and other accessories need to be replaced regularly, and the maintenance cost is high. 4. may be allergic to some people: some people may be allergic to negative ions produced by negative ion generator, headache, cough and other symptoms. In short, negative ion sterilization and purification technology needs to pay attention to controlling ozone concentration, saving energy, reducing maintenance costs and protecting sensitive people during use.
